General Description

The RMK400 Recessed Mounting Kit is designed for use

with System Sensor 100 and 200 photoelectronic or 400 and

500 Series plug-in detectors. As indicated in Figure 1, this

mounting kit provides for the recessed mounting of these

detectors on a junction box with flexible conduit on dry-

wall, suspended ceilings, and other similar surfaces.

Note: All System Sensor smoke detectors can be made

tamper-resistant. However, the use of this capabil-

ity is NOT recommended with the RMK400 Mount-

ing Kit.

The kit consists of:

1 Plastic Recess Mounting Ring

1 Plastic Spacer Ring

1 Metal Mounting Bracket

2 Screws, Type B, No. 8

Mounting Instructions

1. Cut a 4-1/2-inch (115 mm) hole at the desired location

in the mounting surface.

2. Position a 4-1/2 inch junction box at the location of

the hole cut in step 1. Route all wiring to the box

through flexible conduit. Be sure to allow sufficient

conduit and wiring to permit the wired box/conduit

assembly to be pulled through the 4-1/2" hole.

3. Pull the wiring through the box and attach the conduit

to the junction box.

4. Pull the junction box as far as possible through the

hole that was cut in step 1.

5. Attach the Metal Mounting Bracket to the junction

box, using the screw supplied with the junction box.

6. Pull the electrical wiring around the Metal Bracket and

through the center holes in the Recess Mounting Ring,

Spacer Ring, and the Detector Mounting Base. See Fig-

ure 2. Align the holes in the B401 or B501 Detector

Mounting Base and the holes in the plastic Recess

Mounting Ring with the two small holes of the Metal

Mounting Bracket.

7. 100/200 Series photoelectronic detectors only. Snap

the Spacer Ring into place in the Recess Mounting

Ring.

8. Start the two Type B, No. 8 screws, supplied, into the

small holes in the Metal Mounting Bracket and tighten

them until the assembly is just snug. Do NOT tighten

the screws to the point where the Metal Mounting

Bracket begins to deform.

9. Insert this assembly into the mounting hole and hold

it in place while tightening the screws started in step 8

until the assembly is retained in the mounting surface.

10. Wire the detector base, following the instructions pro-

vided with the base.

11. Plug the detector into the base and rotate it clockwise

until it locks into the mounting base.
